This is the real deal if you are looking for a burn. The taste is amazing. As soon as you start your cardio you feel the burn and the sweat is like a waterfall. Definitely does what it’s supposed to do.

Top notch. This pre workout is worth every penny. It is extra clean energy and I have zero jitters or side effects with it. I have been sensitive to other pre workouts in the past and this is the only one that has actually delivered on everything it states. I will never try another brand. It is amazing and I highly recommend!

I love the LFG pre workout! I wake up early and this gets me moving and keeps me pumped for my whole workout. No crash, no jitters, and you can feel the heat. This one is my favorite!

I was a little skeptical on this LFG, but I was pleasantly surprised. This stuff is legit. Since I started taking it I’ve been getting 5-10 more reps in my workouts. Tastes great and it’s definitely upped my workouts.

Tried the LFG burn on a trial run to Kickstart dropping a few pounds, and it did help with that. I did like the taste of it, and the intensity it added to my workouts as well. It has definitely introduced me to a whole new world as far as working out, because I went ahead and ordered a stack to help with reaching my goals of getting in better shape.

Definitely feel the charm of it working after a short while. Usually take it around noon and lasts a few hours. Love the flavor. The Tart Candy is exactly what I want for a mood boost. Used a buy from a different company; but, a similar flavor had creatine which I'm not into. The absence of it in this mix makes it ideal for me and I'll certainly continue to use it.

Haven’t really needed or used pre workout in the past. Tried this recently and wow. After 2 1/2 hours in the gym and I have to make myself leave. Love the taste, not to tart like other pre workouts. Don’t pass this one up, you won’t regret it.

This is the BEST product I’ve ever tried in my life!!! MY FAVORITE!!! 10/5!!!! Nothing in the world like LFG! Never a crash, as a matter of fact I wake up still feeling effects from the day before. I literally can wake up and hit the ground running and then make my LFG! I haven’t felt like this since I was a teen. Actually I’m not sure I’ve ever woke up ready to go. I’ve quit drinking coffee to start my day. I feel energized and there isn’t any snacking throughout my day. LFG is the game changer!!!

The sour scare has been my favorite flavor so far. This is the best workout I've ever tried and really works - it's the perfect amount of caffeine, it works fast and keeps me motivated during my workouts.

So far it's the best pre-workout I've tried. Good flavors too, but I want to specifically give kudos for the Ninja Nectar plum/pear flavor. I was skeptical but it's now my favorite flavor and it's well balanced, not sour nor too sweet. I love this flavor and wish it was also available in low or no stim also for the days when I workout in the afternoon!

WheN bucked up initially offered LFG I was skeptical, but after the first 2 months I was sold! Great flavors and the thermogenic effect helped me break through a stall in my weight loss. Still use LFG as well as BAMF with Racked and Pump for my workouts to be on ???? ???? ????
